Since anything AFTER the sale would be impossible to prove. Pass changes, btc addresses , posts saying " didn't sell it really" etc etc .... the only sure thing you have is the account sales pitch.
If we are tagging account sellers. The sales pitch would be the most important piece of evidence there is.
When you also realize nutildah was screaming account sales = scam facilitating before deciding to sell their own this is an especially damning insight into their character. Certainly looks to be a case for flagging and tagging more than any other account seller who may not be sure they are facilitating scams.
It seems you have dug too deeply timelord, you will now start to see the scammers and abusers/gamers of these current systems of control will come after you. Lauda first then if you keep digging more red and flags will follow. Consider carefully because theymos is not going to come to your aid for uncovering their scamming/gaming/abusing and getting punished by them using his systems of control.
I say keep digging, but of course it is up to you.
They already have come after me:

but that hasn't stopped me from exposing them.
Apologies to Veleor for the mildly OT.
chronicsky in
this post admits to owning three UID's
numanoid, iflewtoday32 and
Vaskiy and using Muhammed Zakir to sell them with Muhammed Zakir using their (chronicsky's) wallet address for payment.
am glad you finally have decided to read what i wrote after two years.
Ignorance is Bliss for some people while it makes other peoples life hard.
Also, thanks for nothing, "Hacked or sold profiles tagged by Veleor" - i have never sold my ID and never will. I do not use any other ID. I have social media accounts and other stuff with same name as well.
